**************************************
*** Python Proxy - A Fast HTTP proxy ***
**************************************
Neste momento este proxy é um Elie Proxy.
Suporta os métodos HTTP:
- OPTIONS;
- GET;
- HEAD;
- POST;
- PUT;
- DELETE;
- TRACE;
- CONENCT.
Suporta:
- Conexões dos cliente em IPv4 ou IPv6;
- Conexões ao alvo em IPv4 e IPv6;
- Conexões todo o tipo de transmissão de dados TCP (CONNECT tunneling),
p.e. ligações SSL, como é o caso do HTTPS.
A fazer:
- Verificar se o input vindo do cliente está correcto;
- Enviar os devidos HTTP erros se não, ou simplesmente quebrar a ligação;
- Criar um gestor de erros;
- Criar ficheiro log de erros;
- Colocar excepções nos sítios onde é previsível a ocorrência de erros,
p.e.sockets e ficheiros;
- Rever tudo e melhorar a estrutura do programar e colocar nomes adequados nas
variáveis e métodos;
- Comentar o programa decentemente;
- Doc Strings.
Funcionalidades futuras:
- Adiconar a funcionalidade de proxy anónimo e transparente;
- Suportar FTP?.
(!) Atenção o que se segue só tem efeito em conexões não CONNECT, para estas o
proxy é sempre Elite.
Qual a diferença entre um proxy Elite, Anónimo e Transparente?
- Um proxy elite é totalmente anónimo, o servidor que o recebe não consegue ter
conhecimento da existência do proxy e não recebe o endereço IP do cliente;
- Quando é usado um proxy anónimo o servidor sabe que o cliente está a usar um
proxy mas não sabe o endereço IP do cliente;
É enviado o cabeçalho HTTP "Proxy-agent".
- Um proxy transparente fornece ao servidor o IP do cliente e um informação que
se está a usar um proxy.
São enviados os cabeçalhos HTTP "Proxy-agent" e "HTTP_X_FORWARDED_FOR".
